Contact trajectory of angular contact ball bearings under dynamic operating condition
Tribology International, 2016Abstract A contact trajectory model of ball bearings under the dynamic condition was developed by the means of the development of the integrated multi-body dynamics and multi-freedom kinematics with the multi-interfacial contact mechanics. Subsequently, the general methodology was employed to investigate the dynamic contact performance of ball ...

Ball-Ball Load Carrying Capacity in Retainerless Angular-Contact Bearings
Journal of Lubrication Technology, 1982Load carrying capacity between the balls in a retainerless bearing, theoretically zero, is shown experimentally to be large enough to allow for full complement operation.

Precessional slip in an angular contact ball bearing
Wear, 1982Abstract A previously reported ball precessional motion in an angular contact bearing is analyzed. Explicit forms for ball-race slip are given, both with and without precession. Slip and entrainment velocity at ball-ball contacts in a retainerless bearing are also given, also with and without precession.

Effect of race conformities in angular contact ball bearing
Tribology International, 2016Abstract The determination of race conformity of ball bearing is mainly based on the classical fatigue life theory; however, besides the fatigue life, skidding may also become the main concern due to high frictional heating in high-speed application; therefore the strategy of race conformity determination should be changed accordingly.

Slip Measurement in an Angular Contact Ball Bearing
Journal of Lubrication Technology, 1983An experimental method for ball-race slip measurement that includes a method for determining the geometry of an assembled bearing from easily and accurately measured parameters is presented herein. Slip measurements taken with four fluid lubricants are discussed in terms of quantity, structure, bulk properties, and degradation.

Angular Contact Ball Bearings for a Rear Axle Differential
SAE Technical Paper Series, 2003<div class="htmlview paragraph">In passenger car axle differentials, axially preloaded tapered roller bearings have been used exclusively since their rigidity and life are sufficient for this application. In real life applications, the bearing preload during transmission life is reduced due to wear in the contact between the roller and the rib ...

Dynamic characteristics of high speed angular contact ball bearings
Wear, 1997Abstract A theoretical research was developed concerning the rigidity and damping characteristics of high speed angular contact ball bearings mounted on grinding machine main spindles. Both film squeeze effects and elastic deformation of the Hertzian contact were considered and an adequate dynamic model is suggested. To validate the results obtained,

Angular Contact Ball Bearings: Track Position at High Speeds
Proceedings of the Institution of Mechanical Engineers, 1969The track position of the balls on the outer race of an angular contact bearing of the series and size used on the main shaft of aero gas turbine engines was measured in a test rig. The test rig was capable of simulating the operating conditions of the bearing with respect to axial load, inner race speed and high lubricant flow rates.
